On Wednesday's Tonight Show, Blake Shelton taught Jimmy Fallon how to treat his new truck.

"You keepin' it clean?" Blake asked. "Is it lookin' nice?"

"It's pretty clean," Jimmy responded.

"That's wrong!" Blake exclaimed. "You gotta have mud on it, dents in it and scratches, guts in the back, corn and shovels. That's just crap. Trucks are a tool, you don't go drivin' around the city in it."
